The four elastic yarns F2 are covered by a method described below using four corresponding cover yarns F1.

  Each winding station 1A is provided with a false twist unit 19. The false twisting unit 19 is arranged in the upper part of the supply zone 15. The false twist unit 19 is well known and will not be described in detail here. Advantageously, the number of false twisting units 19 for each winding station 1A is the same as the number of yarns F1 fed from each creel 7A, 7B towards the operating front of the device 1.

  In the supply zone 15, a guide roller 21 is provided for each yarn F1. The guide roller 21 changes the direction of the yarn F1 toward each of the pair of supply rollers 23 and 25. In some embodiments, roller 23 is motor driven and roller 25 is an idle roller. In FIG. 3, the two rollers 23, 25 are shown spaced apart from each other, but during the operation of the device 1, the distance between the rollers 23 and 25 is such that the two rollers contact each other. The yarn F1 is formed between the rollers 23 and 25 so as to form a nip through which the yarn F1 passes. In this method, one or a plurality of yarns F <b> 1 are supplied to a member disposed below by controlled rotation of the motor driving roller 23. In the embodiment shown (FIG. 4), the rollers 23 and 25 may have an axial length adapted to engage a single yarn F1. In this method, each yarn F1 is drawn by being sandwiched between each of the pair of rollers 23 and 25. The rollers 23 can advantageously be fixed to a common drive shaft 23A, and the rollers 25 can be supported independently of each other on a free-standing spindle.

  Using a roller 23 and / or 25 having a large axial dimension, a single pair of rollers 23 and 25 (or one roller 23 and a plurality of rollers 25, or one roller 25 and a plurality of rollers 23) are used. It is also possible to engage with a plurality of yarns F1 supplied simultaneously.

  In particular, as shown in FIG. 3, each yarn F1 is almost vertical from the pair of supply rollers 23 and 25 toward another pair of rollers 27 and 29 arranged at positions below the pair of rollers 23 and 25. Through a trajectory. Advantageously, one of the rollers 27 and 29, for example roller 27, is motor driven, while the other, for example, roller 29 is an idle roller. In FIG. 3, rollers 27 and 29 are shown spaced apart, but during operation of the apparatus, rollers 27 and 29 are adjacent to each other and yarn F1 is sandwiched between rollers 27 and 29. Then, the roller 27 is pulled in by the rotation. Reference numeral 27A denotes a common drive shaft, and the motor drive roller 27 can be provided on the drive shaft 27A.

  Extending downstream of the pair of rollers 27 and 29 is a track along which the yarn F1 travels together with the elastic yarn F2 supplied from the corresponding bobbin B2.

  As described above, each winding station 1A having four winding positions 17A to 17D is provided with four bobbins B2 of elastic yarns, and these bobbins B2 are described below with reference to FIGS. 6A to 6C. It is supported by each support means 20 described in detail. Each support means 20 can hold each bobbin B of the elastic yarn F <b> 2 in contact with the motor-driven unwinding roller 22. As will become apparent below, each support means 20 moves the bobbin B2 away from the motor driven unwinding roller 22, discharges the empty bobbin B2, and replaces it with the bobbin B2 of the new elastic yarn F2. Or it may be movable to perform other operations.

  The unwinding roller 22 associated with the bobbin B2 of the elastic yarn F2 can be provided on a common drive shaft 22A.

  In the embodiment shown in FIG. 3, the parallel trajectories of the yarns F <b> 1 and F <b> 2 pass through the interlacing jet 31. In the interlacing jet 31, the elastic yarn F2 is covered by the covering yarn F1 in a known manner. The latter covering yarn F1 actually consists of a plurality of filaments having a micrometer cross section. When passing through the interlacing jet 31, the filament forming the covering yarn F1 regularly covers the elastic yarn F2 with a degree of difference.

  Accordingly, the synthetic yarn FC formed by the elastic yarn F2 covered by the covering yarn F1 is supplied from the interlacing jet 31.

  Downstream of the interlacing jet 31, a yarn guide 33 made of, for example, ceramic can be provided for each synthetic yarn FC, and the synthetic yarn FC is used as a currency for the yarn guide 33. Downstream of the yarn guide 33, a path of the synthetic yarn FC extends through a nip formed between another pair of rollers 35 and 37. In some embodiments, roller 35 may be motor driven and roller 37 may be an idle roller. The roller 35 can be provided on a common drive shaft 35. The idle rollers 37 can be supported independently of each other.

  In the schematic of FIG. 3, the rollers 35 and 37 are shown spaced apart from each other with a spacing greater than the effective spacing during operation of the device. In fact, in operation, the rollers 35 and 37 are adjacent to each other and form the feed nip of the synthetic yarn FC. The synthetic yarn FC sandwiched between the rollers 35 and 37 is drawn in by the rotation of the motor drive roller 35 and advances, for example, along a trajectory that can pass through another yarn guide 38 and 39. In known manner, a system can be provided between the yarn guides 38 and 39 for oiling the yarn.

  Four winding positions 17 </ b> A to 17 </ b> D that are overlapped with each other are arranged at a height lower than the interlacing jet 31 and the pair of rollers 35 and 37. The four synthetic yarns FC trajectories fed to the four mutually stacked winding positions 17A to 17D extend downward from each pair of rollers 35 and 37 and are formed at each winding station 1A. Of the synthetic yarn FC is supplied to the winding positions 17A to 17D. In FIG. 3, four synthetic yarns FC supplied to the four windings 17A to 17D are indicated by FCA, FCB, FCC and FCD, respectively.

  In some embodiments, each winding position 17A-17D may have a support means 41 for each winding tube T in which the bobbin B3 of the synthetic yarn FC is formed. In some embodiments, a winding operation according to the arrow fB3 is provided to each bobbin B3 by a corresponding winding roller 43 provided at each winding position 17A-17D. In FIG. 3, the support means 41 at the four winding positions 17A to 17D are indicated by reference numerals 41A to 41D. Similarly, the motor-driven winding rollers for the four winding positions 17A to 17D are indicated by reference numerals 43A to 43D. It is shown in

  In the state shown in FIG. 3, each support means 41A-41D is positioned so as to support each bobbin B3 at the highest height with respect to each motor drive roller 43A-43D. Furthermore, during the effective winding of the synthetic yarn FC, the positions of the support means 41A-41D are such that the outer surface of the formed bobbin B3 maintains contact with each motor driven winding roller 43A-43D, and It is made to press against it. In this method, the formed bobbin B3 rotates due to friction between each motor driven take-up roller 43A-43D and initially the tube T and then the outer surface of the formed bobbin B3. Is maintained.

  Each winding position 17A-17D may advantageously have a traversing device that is used to evenly distribute the synthetic yarn FC along the axial length of each bobbin B3. This traversing device gives the yarn a reciprocating motion parallel to the winding axis of the tube T during winding. The traversing apparatus is generally indicated by reference numerals 45A to 45D with respect to the winding positions 17A to 17D arranged at the operating fronts of the apparatus 1 at each winding station 1A.

  In an advantageous embodiment, the motor-driven rotating member of each front 3A and 3B of the device 1 described above can be driven by a continuous shaft extending from one of the two opposing heads of the device 1 to the other. A continuous shaft is intended as a mechanical part that can also consist of several parts, lengths or members interconnected by suitable joints, but advantageously and preferably each shaft is a head 5 is rotated by a single motor provided in 5.

  In practice, the motor-driven rotating member arranged along each operating front 3A and 3B of the device 1 comprises a supply roller 23 for the covering yarn F1, a supply roller 27 for supplying the elastic yarn F2 and the covering yarn F1. , Motor drive supply roller 35 of synthetic yarn FC, unwinding roller 22 of elastic yarn F2, four winding devices, that is, motor driven winding rollers 43A to 43D at winding positions 17A to 17D and respective operating fronts 3A and 3B 4 are the four drive shafts of the traversing device units 45A to 45D in the winding position arranged four times. FIG. 7 shows a practically possible and advantageous arrangement of the electric motor of the head 5 of the device 1 for operating the motor-driven rotary member described above.

  More specifically, referring to FIG. 7, for each front 3A and 3B of the apparatus 1, the first electric motor 51 controls the rotation of the common shaft 23A on which the motor drive supply roller 23 of the covering yarn F1 is provided. Is provided to do.

  Under the motor 51, another motor 53 for rotating the drive shaft 22A on which the bobbin unwinding roller 22 of the elastic yarn B2 is provided may be provided.

  The shaft 27 </ b> A on which the supply roller 27 is provided can be rotated by the third motor 55.

  Advantageously, in some embodiments, a fourth motor 57 rotates the roller 35 provided on the shaft 35A.

  In this method, the rotational speeds of the supply rollers 23, 27 and 35 and the unwinding roller 22 can be controlled independently.

  The motor-driven take-up rollers 43A-43D at the four take-up positions 17A-17D of each front 3A and 3B of the device 1 can advantageously be actuated by a pair of motors. Each motor rotates the two drive shafts of the winding roller at two adjacent winding positions. In some embodiments, the motor 59 rotates shafts 61 and 63 to which the winding rollers 43A and 43B at the winding positions 17A and 17B are attached. Advantageously, in some embodiments, an endless flexible member, for example, a belt, preferably a toothed belt 65, may be provided, the endless flexible member from the common motor 59 being two substantially parallel. The movement is transmitted to the shafts 61 and 63, and as a result, the series of motor-driven take-up rollers 43A and 43B rotate substantially synchronously.

  Another motor 67 may be provided below the motor 59, and the motor 67 rotates shafts 69 and 71 to which the motor-driven take-up rollers 43C and 43D are attached, respectively. An endless flexible member, such as a toothed belt 73, can transmit motion from the motor 67 to the two shafts 69 and 71. By this method, synchronized rotation of the motor driven winding rollers 43C and 43D at the winding positions 17C and 17D is obtained.

  In an advantageous embodiment, another motor 75 rotates the shaft 77 that controls the traversing device 45A at the first winding position 17A and the second working shaft 79 of the traversing device 45B at the second winding position 17B. Let A flexible member, such as a toothed belt 81, transmits movement from the motor 75 to the drive shafts 77 and 79 of the traversing devices 45A and 45B. Accordingly, the traversing devices 45A and 45B are controlled to be synchronized by the common motor 75.

  Similarly, another motor 83 may be provided to rotate the drive shaft 85 of the traversing device 45C at the winding position 17C and the drive shaft 87 of the traversing device 45D at the winding position 17D. An endless flexible member, such as a toothed belt 89, may be provided to drive the drive shafts 85 and 87 synchronously so that the traversing devices 45C and 45D are controlled synchronously.

  In fact, in this advantageous embodiment, the winding positions 17A-17D are divided into two groups, each group having winding positions 17A and 17B and winding positions 17C and 17D. Each aligned pair of winding positions has an independent operating motor relative to the other pair of motors aligned in the winding position. Motors 59 and 75 control movable members (winding rollers and traversing devices) at winding positions 17A and 17B, and motors 67 and 83 move movable members (winding rollers and traversing) at winding positions 17C and 17D. Device).

  The motors 59 and 75 can be controlled independently of the motors 67 and 83, and the supply trajectory of the synthetic yarn FC from the nip defined by the rollers 35 and 37 to each take-up bobbin B3 is arranged in each bobbin B3. Due to the heights being made, the fact that they have significantly different lengths can be taken into account. Since the motors 59 and 75 and the motors 67 and 83 act independently, even if the length of the supply track is different, substantially the same bobbin B3 can be obtained. It makes it possible to compensate for fluctuations in the supply state. In fact, the rotational speed of the winding rollers 43C and 43D can be varied with respect to the rotational speed of the winding rollers 43A and 43B, and the speed of the reciprocating motion of the traversing devices 45C and 45D can be determined by the traversing. It is also possible to vary for the corresponding speed of the devices 45A and 45B. The speed variation can compensate for different supply tensions generated along the trajectory to different lengths of yarn FC from the nip between rollers 35 and 37 and the winding position of each bobbin B3.

  The use of independent motors provides additional advantages for two stacked pairs of winding units. Specifically, the device thus configured allows two yarns to be fed and processed simultaneously along two separate trajectories and wound them on one final bobbin B3. Makes it possible to take. Thus, in each section with four winding units and four yarn tracks, all four tracks, but only two winding units are used to form two bobbins at the same time, The yarn of the book will be wound. When the device is operating in this manner, one of the two motors can be driven so that all the components controlled thereby remain stationary.

  According to an advantageous embodiment, in order to obtain a more compact structure of the bobbins B2 of the elastic yarns F2, in particular the dimensions are adapted to the shape of the support means 20 of these bobbins B2. In fact, it is advantageous to arrange all the bobbins B2 of the elastic yarns F2 at the same height so as to eliminate the difference in the supply state of the separate elastic yarns F2 to the interlacing jet 31. For this purpose, the support means 20 must be configured such that the four bobbins B2 of elastic yarn are arranged in an occupied area corresponding to the axial dimension of the winding bobbin B3. In this way, the bobbins of the elastic yarn F2 can be arranged substantially coaxially with each other, and thus substantially for each of the four elastic yarns F2 fed to the four lower winding positions. The same trajectory can be defined, which is advantageous for homogenizing the production status of the separate bobbins B3 of the synthetic yarn FC.

  In order to facilitate the processing of the bobbin B2 of the elastic yarn in the step of replacing the empty bobbin with a new bobbin and, for example, if the elastic yarn experiences an unexpected break with a need for repair, In this embodiment, a special form of support means 20 shown in FIG. 3 is provided. Details of additional structure and operation of an embodiment of the support means 20 are described below with reference to FIGS. 6A to 6C are axonometric views showing portions of the region where the support means 20 is arranged at different operating positions.

  In some embodiments, each support means 20 includes an arm 91 provided on a fixed structure 93 of the device 1. Advantageously, each arm 91 can be pivoted to the structure 93 at the position of the fulcrum 91A and can be pivoted around the fulcrum 91A according to the double arrow f91.

  6A and 6B show two different angular positions of the arm 91. In FIG. 6A, the arm 91 is positioned at an angular position such that the outer surface of each bobbin B2 of the elastic yarn F2 contacts the cylindrical outer surface of the unwinding roller 22. In this state, the bobbin B2 rotates in the unwinding direction through friction by the rotation of the unwinding roller 22. It is understood that when the bobbin B2 contacts the unwinding roller 22, the position where the arm 91 is placed changes according to the diameter of the bobbin B2. As a result of the consumption of the elastic yarn F2, as the diameter of this bobbin decreases, the arm 91 rotates by gravity, that is, rotates downward, and the contact between the outer surface of the bobbin B2 and the outer surface of the unwinding roller 22 occurs. To maintain.

  FIG. 6B shows the highest raised position of the arm 91 of the support means 20 of the bobbin B2 of the elastic yarn F2. In this position, the core of each bobbin B2 of the elastic yarn F2, ie the flange A2, is preferably fixed to the fixing structure 93 of the device in an angular position which can be adjusted, for example, by means of screws 99 and slots 100. The position is in contact with each brake 95 supported by the bracket 97. By adjusting the angular position of the bracket 97, the position of the brake 95 can be adjusted to the diameter of the flange of the bobbin B2 of the elastic yarn F2, that is, the diameter of the core A2.

  In the position of FIG. 6B, pressing the flange of bobbin B2, ie, core A2, against brake 95, for example, when bobbin B2 is used up and must be replaced, or to carry out the operation, For example, the rotation of the bobbin B2 is stopped in order to resume the supply of the elastic yarn after the breakage.

  In some embodiments, the upward pivoting motion of each arm 9 can be provided by each actuator 103, for example, a pneumatic or hydraulic piston-cylinder actuator. Gradually downward movement as the bobbin diameter decreases can be obtained through gravity.
